Item Revisão bibliográfica sobre a implementação da Lei 13.415/17: desafios, mudanças, impactos e dificuldades frente ao novo ensino médio no ensino de química(2023-09-20) Barros, Celmalice Vicente Oliveira; Silva, Suely Alves da; http://lattes.cnpq.br/3497194749381919The educational system in Brazil has undergone several historical transformations since the arrival of the colonizers. The secondary education reform, promoted by Law nº 13,415 of 2017, sought to face challenges such as school dropout and low results in evaluations. This reform brought significant changes, such as curriculum flexibility and an increase in the annual workload from 800 to 1400 hours. The training itineraries allowed students to choose areas of interest, such as Languages, Mathematics, Nature Sciences, Human Sciences and Technical and Professional Training. However, there were intense debates about the implementation of the reform. In this research, our goal is to analyze the conceptions of some authors about the implementation of Law 13.415/17 and what are the challenges and difficulties facing the New Secondary School in Chemistry Teaching. This monograph is theoretical, a bibliographical research was carried out on the implementation of Law 13.415/17. The results indicated that the Brazilian Society of Chemistry (BSC) expressed concerns, highlighting the possible reduction of specific contents such as Chemistry, as well as the lack of structure in public schools to support the changes. Teachers and specialists also raised concerns about teacher training and inequality between public and private schools. The reform of secondary education reflected the search for adequacy to social demands and the labor market. Despite the modernization intentions, its implementation faced challenges, such as the need for continuous teacher training and the guarantee of equal opportunities for students from different contexts. Such findings show that the reform sought to innovate Brazilian secondary education, but also generated debates about its implications for the quality of education and educational inequalities.Item Análise das relações entre Ciência-Tecnologia-Sociedade (CTS) nas questões de química do Exame Nacional do Ensino Médio edição 2021(2022-05-31) Oliveira, Brenda Silva; Firme, Ruth do Nascimento; http://lattes.cnpq.br/7234636790850019; http://lattes.cnpq.br/8709791672347257The National High School Exam (Enem) is a national assessment created in 1998 with the objective of evaluating students' performance at the end of basic education. In 2009, it was reformulated and started to be used as an instrument for entering higher education with the aim of democratizing opportunities for access to higher education. The exam aims to assess the quality of basic education and encourage the restructuring of the school curriculum. In this research, the Enem is also conceived as an indicator of the presence of the science-technology-society (CTS) approach in high school. Therefore, the objective of this work is to analyze the CTS relationships established in the questions related to the chemical contents of the Natural Sciences notebook and its technologies of the Enem in the 2021 edition. we carried out a documentary research with a qualitative approach to the data, which considered quantitative data. For the analysis, assumptions of the Discursive Textual Analysis were considered. Based on the results of the analysis, it can be said that: most of the questions covered different themes, with a predominance of the theme of environmental pollution; most questions explored scientific and technological aspects; and Science-Technology, Science-Society, Technology-Society and Science-Technology-Society relationships were identified, with a predominance of the former. In this sense, considering that in the CTS approach the three dimensions are articulated, it is concluded that this type of approach seems to be still incipient in the teaching of Chemistry in Brazilian High Schools.Item Biossensor como proposta alternativa para o ensino de eletroquimica(2018) Guerra, Angela Cecília Soares; Souza, Sandra Rodrigues de; Freitas, Kátia Cristina Silva de; http://lattes.cnpq.br/5859266863241551; http://lattes.cnpq.br/4678692939311710We report an investigation directed to the speeches that occurred as the students of the 3rd year of high school in a public school located in the neighborhood of Santo Amaro / Recife-PE, aiming to analyze the biosensor theme as a didactic proposal complementary to the teaching of electrochemistry. For that, a sequence of activities involving diagnosis, expository class, and dialogue, experimentation, contextualization and problematization were elaborated. Results showed that it is possible to work with the biosensor theme in high school to encourage students to use scientific knowledge. The students who presented difficulties in understanding the chemical concepts of oxidation / reduction and pile after didactic strategies used is a result that is acceptable because the contents involve the principles of electrochemistry have often been pointed out by teachers and high school students as one of the issues that represents great difficulties in the teaching-learning process. Due to the good performance of the students who were willing to participate in this research we can consider that the proposal proved to be a useful strategy for the production of answers and explanations about the knowledge of the principles of electrochemistry. Even for the students who did not reach the understanding of this content, the results indicated that actions like this can be a tool that helps the students to become aware of how they understand the difficulties involved in the concepts of electrochemistry issues.
